Hi! I understand you're seeing that persistent "Something went wrong. Please try again later" message on the Customer Spark app, and reinstalling didn't help you log in. That can definitely interrupt things. Let's work through this together.

First, to make sure I cover the right steps:

1. When did this issue start occurring? Was it after an update or did it just suddenly begin?
2. Have you tried clearing the app cache and data on your Android 10 device? Sometimes leftover data can cause login issues.
3. Are you connected to Wi-Fi or cellular data? Occasionally network issues trigger such messages.
4. Do you have the latest version of the Spark app installed from the official source?

Here’s a step-by-step approach I’d recommend:

Step 1: Clear Cache and Data
- Go to Settings > Apps > Customer Spark app.
- Tap on Storage.
- Select Clear Cache first, then Clear Data.
- Then try opening and logging in again.

Step 2: Check Network Connection
- Switch between Wi-Fi and mobile data to see if one works better.
- Try restarting your router if on Wi-Fi.

Step 3: Ensure App is Updated
- Visit Google Play Store.
- Search Customer Spark.
- If “Update” is available, apply it and then retry login.

Step 4: Device Date & Time Settings
- Incorrect device date/time can cause server communication issues.
- Set your Android device to Automatic date & time in Settings > System.

Step 5: Check for Service Outages
- Sometimes the Spark server might be down or experiencing high traffic.
- I found conversations about similar issues on Reddit and Facebook groups recently, so it might be temporary on their side12.

If after these steps you still can't log in, it might be worth:
- Trying on a different device if possible to isolate device vs account issues.
- Contacting Spark support directly via [email protected] for account-specific assistance.

Could you try these steps and let me know if anything changes? I'll help you further based on what you find.
